Abstract

PROBLEM TO BE SOLVED: To provide the striker installing structure of an automobile side door which is capable of enhancing the strength of a reinforcing panel by means of simple installing structure. SOLUTION: A quarter panel 3 is bent toward the outside of a car interior in the rear part of a door opening part 2 for a side door in order to form a door opening peripheral surface 2a. The panel 3 is further bent forward, leaving a void part 5, and then extended in the forward direction of the automobile together with a wheel house outer 4, which is located at more outer side of the car interior than the void part 5, in order to form a door opening edge part 2b. A striker 8 is installed in a reinforcing panel 10, which is spot-welded to the door opening peripheral surface 2a and the tip end part of which is held between the quarter panel 3 and a tip end flange part of the wheel house outer 4 so as to be spot-welded. The reinforcing panel 10, which is spot-welded to the door opening peripheral surface 2a, is extended toward the inside of the car interior so as to form an abutting surface 11, which abuts on the wheel house outer 4, and the abutting surface 11 is plug-welded to the wheel house outer 4.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening edge which is joined to a peripheral surface of a door opening at a rear portion of a door opening for a side door and has a space formed by a quarter panel and a wheel house outer. The present invention relates to a striker mounting structure for an automobile side door for mounting a striker that engages with a latch on a side door side to a bent and joined reinforce panel.

[0002]

2. Description of the Related Art A striker mounting structure for a side door of a car of this type is obtained by bending a quarter panel 3 toward the outside of a vehicle as shown in FIG. It is spot-welded to the formed door opening peripheral surface 2a, and is bent so as to enter the door opening edge 2b, which forms a space 5 with the wheel house outer and 4 to improve the surface rigidity as a bone. The striker 8 is attached to the reinforce panel 9 spot-welded with the front end portion sandwiched between the front end flange portions 3c and 4a. This reinforce panel is bent into an L-shape to secure a reinforcing effect by fixing its tip, but when the side door is closed in the direction of arrow A because the corner is floating in the space 5, a dotted line is formed. As a result, the door closing sound or the unlocking sound of the lock coming off the striker 8 is increased.

On the other hand, according to Japanese Utility Model Laid-Open Publication No. 63-168165, a curved portion of a reinforce panel having a similar shape is made to enter the door opening edge 2b, and the front end is held between the front flanges 3c and 4a. Instead of joining, it is well known that at least one of the inner and outer panels forming the door opening edge 2b is bent so as to approach each other and clamped and welded.

[0004]

In this case, it is necessary to deform the panel, which is not preferable in terms of manufacturing cost, and spot embossing is visible and the appearance is not good.

SUMMARY OF THE INVENTION In view of the foregoing, an object of the present invention is to provide a striker mounting structure for an automobile side door which can improve the strength of a reinforcement panel of the kind mentioned at the beginning with a simple mounting structure. I do.

[0006]

According to the present invention, in order to achieve this object, according to the present invention, the rear portion of the door opening for the side door is formed by bending the quarter panel toward the outside of the cabin to form a peripheral surface of the door opening. It is formed so that it is bent forward and the space is placed in the front of the vehicle to extend the front of the vehicle together with the wheel house outer outside the cabin to form a door opening edge, and is spot welded to the door opening peripheral surface. A striker that engages with a latch on the side door side is attached to a reinforce panel spot-welded with the tip bent so as to penetrate into the space between the quarter panel and the tip flange of the wheel house outer. In the structure for mounting a striker on the side door of an automobile, the reinforcement panel spot-welded to the door opening And forming an abutment surface abutting the wheel house outer, characterized in that the plug welding the contact surface to the wheel house outer.

[0007] The reinforce panel has its contact surface supported by the wheel house outer and is restrained from being displaced in the door closing direction together with the door opening peripheral surface when the door is closed, and the tip is also fixed to the door opening edge. By doing so, a closed cross section of the space is formed to improve the rigidity of the contact surface.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A striker mounting structure for a side door of an automobile according to an embodiment of the present invention will be described with reference to FIGS. The rear part of the door opening 2 of the side door 1 is formed by bending the quarter panel 3 toward the outside of the cabin to form a door opening peripheral surface 2a with a curved portion 3a facing the front of the vehicle, and further bent at a right angle to the front of the vehicle. The curved portion 3b along the vehicle front-rear direction is configured to extend forward of the vehicle together with the wheel house outer 4 serving as an inner panel on the vehicle cabin side with the space portion 5 therebetween to form a door opening edge 2b. .

Reference numeral 10 denotes a reinforce panel for attaching a striker 8 to be engaged with the latch 7 on the side door side. The reinforcement panel 10 is formed in an L-shape, and a corner portion has a portion joined to the peripheral surface 2a of the door opening. A concave contact surface 11 extending to the indoor side and contacting the wheel house outer 4 is formed. The reinforcement panel 10 is spot-welded to the peripheral surface 2a of the door opening, and bolts the seat of the striker 8 through the bolt hole 15. The tip portion 12 of the portion bent into the space 5 is the quarter panel 3
And, it is spot-welded between the front flange portions 3c and 4a of the wheel house outer 4 bent toward each other. Next, the contact surface 11 is plug-welded from the welding hole 4b of the wheel house outer 4.

Accordingly, the reinforcement panel 10 is provided.
The L-shaped end portions are welded and fixed, so that the rigidity of the door opening peripheral surface 2a in the vehicle width direction and the vehicle front-rear direction is improved, and the corner portion is extended as it is along the opening peripheral surface 2a. By being fixed to the house outer 4 by welding, rigidity in the vehicle width direction is improved. Therefore, the rigidity in the door closing direction is further improved, and the generation of the door closing sound and the release sound is suppressed.

[0011]

According to the present invention, the rigidity of the side door of the reinforce panel in the closing direction can be improved only by its deformation, and the door closing sound and the release sound can be suppressed.
